For several different Abis MO, osmo-bts appears to accept OPSTART despite no attributes having been set before.

This makes our BTS_Tests_OML fail, likely ever since those tests were written:

• BTS_Tests_OML.TC_bts_opstart_noattr
  • RADIO CARRIER: Test OPSTART without SET BTS ATTRIBUTES; expect NACK
  • error: Unexpected OPSTART ACK for NM_OC_BTS (1) { bts_nr := 0, trx_nr := 255, ts_nr := 255 }
• BTS_Tests_OML.TC_radio_carrier_opstart_noattr
  • RADIO CARRIER: Test OPSTART without SET BTS ATTRIBUTES; expect NACK
  • error: Unexpected OPSTART ACK for NM_OC_RADIO_CARRIER (2) { bts_nr := 0, trx_nr := 0, ts_nr := 255 }
• BTS_Tests_OML.TC_ts_opstart_noattr
  • BTS: Test OPSTART without SET BTS ATTRIBUTES; expect NACK
  • error: Unexpected OPSTART ACK for NM_OC_CHANNEL (3) { bts_nr := 0, trx_nr := 0, ts_nr := 1 }
